I’m doing a simple menu with ncurses. It works for cygwin, but not in linux – home or end keys end the program immediately. I think handling of excape (27) has something to do with it because if I don’t handle it in linux home and end have no effect. in cygwin – home, end and esc work fine (of course escape usually works which delay as it aways did in linux).

in my event loop I do this

  while (true) {
    clearScr = false;
    c = wgetch(menuWin);
    switch (c) {
      case KEY_HOME: {
        code = menu_driver(menu, REQ_FIRST_ITEM);
        break;
      }
      case KEY_END: {
        code = menu_driver(menu, REQ_LAST_ITEM);
        break;
      }
      case 27: {// Esc key - if I remove this home and end still doesn't work but they don't quit the program
        if (!isSubMenu) {
          // Handle cancel logic
          //are you sure?
        }
        return;
      }
...

I’m doing this when I create the menu

keypad(menuWin, TRUE);

my ncurses init/cleanup code:

void initialize_ncurses() {
  initscr();
  cbreak();
  noecho();
  keypad(stdscr, TRUE);
  intrflush(stdscr, FALSE); // Prevent flush on interrupt keys - ChatGPT advice
  start_color();
  init_pair(1, COLOR_WHITE, COLOR_BLUE);
  init_pair(2, COLOR_YELLOW, COLOR_BLUE); // Selected text color pair
  init_pair(3, COLOR_WHITE, COLOR_BLACK);
}

void cleanup_ncurses() {
  endwin();
}

I’m connecting to linux via putty. putty keyboard settings:
